What to make of it
« on: April 04, 2017, 10:12:11 AM »
In an effort to keep the Black Dog at bay, i,ve decided to make something. I found a block of alloy in the man cave and thought " I must be able to make something out of this ". So, i,ve started making another gun thingy. Why thingy? Because I don,t know what its going to be yet.  :o It,s a small block so therefore it will have to be something small. I,ve ordered another 13cu inch bottle to use with it so I guess it will turn out to be a mini ratter . I,ll have to design and make a stock ( I hate woodworking ) . I was thinking a laminated one. Never used that stuff before so should be interesting. It will take a while to make as i,m designing it as I go along, ( never done that before either ). So, be patient folks and bare with me  ;) I,ll also try to take stage by stage pictures this time.

Hi, Baggy.

Just to clarify; you've found a block of alloy and ordered a bottle and with that as a starting point you've decided to "make something"?

As a total inadequate when it comes to engineering, I'm fascinated.

How do you approach something like that?

How big is the block of alloy?

What tools will you use to turn the block into something else?

What other bits and bobs will you need to source/manufacture?

At what point will you have to settle on a design/goal?

Bagga, can you use the bottle as part of the stock? What about a fiber glass stock with wood inserts for the cheak peace and grips?

The block is approximately 25mm x 56mm x 110mm. Most of the work is done using a milling machine. In my case I have a lathe/mill combo. All the holes for the barrel , valve , hammer and resevoir are done using the mill as are the scope dovetails and the trigger housing. All other holes for pins, grub screws etc. are drilled also using the mill. Machining the barrel , hammer , valve and odd plugs are done on the lathe. The trigger parts are made using a good old hacksaw and the mill then hardened using a blow torch. I,ve just finalised the drawing having already started the machining. Yes , I know , a crazy way to go about things but, hey, it will all come good in the end  :D . I,m using one of the 13cu. inch bottles because they are regulated and cheap ( 35 ). That means I should get plenty of shots ( if the bloody thing works  ;D ) I,ll have to get the thing working then design a stock to fit it. Should be a laugh. I don,t care really because its keeping my old mind working.

After seeing your previous creations, I'm already intrigued as to how this one/design will turn out.

All I can say is 'let your juices flow' mucker.........and please keep us informed with regular updates and plenty o' pics as the build progresses please? Ta.  :-* ;)

Nice to see you at it in the workshop again. Be careful near electric if your juices are flowing though  ;D

Great stuff, Baggy.

What would you call the bit that the block of alloy is to become?

What metal will you use to make the barrel? Does it material matter?

Will all the component parts screw together (in the style of the gun used by Edward Fox in "Day of the Jackal") or will it many need to be welded?

Will it be a .22?

Pics?

Because the block contains all of the working components I suppose it could only be called the main housing.
I don,t make barrels I buy them in. I have a few old ones to choose from.
It will be a .177. as are all but one of my guns.
It wont be a takedown, it will just be different.
Goodness knows what it will look like. I will get it working first then design a stock around it. I doubt it will be very powerful as there,s not a lot of room to fit a decent sized hammer. We,ll see.
Yipee, the bottle has just arrived. Now I just have to order a couple of BSP taps and a die and it will be full steam ahead.
Watch this space.

How does the size of the hammer affect power? (I didn't even realise airguns HAD hammers!!)

Pcp and co2 have hammers that knock open the valve to release the air to fire the pellets  ;)
